Check These Out

Uptime in minute
Want to run scripts/programs in the system after starting X minute [ For letting the system to free ]? This will give uptime in minute.

String to binary
Cool but useless.

find filenames and directory names that doesn't conform ISO 9660 level 2
You might want to check what file and directory names would be renamed or chopped if you create iso 9660 level 2 image out of them. Use this command to check first.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Copy uncommitted changes from remote git repository
Copy changed files from remote git repository, _including binary ones_, staged and unstaged alike. Note that this command doesn't handle deleted files properly.

Monitor the queries being run by MySQL
Watch is a very useful command for periodically running another command - in this using mysqladmin to display the processlist. This is useful for monitoring which queries are causing your server to clog up. More info here: http://codeinthehole.com/archives/2-Monitoring-MySQL-processes.html

Auto-log commands
A quick alias I use right before logging into a server so that I have a log of the transactions as well as the ability to re-connect from another computer. Useful for when your boss says "what commands did you run again on that server?" and you had already closed the terminal ;) I wrapped it in a script now, with more features, but this is the heart of it. Never leave home without it.

NSA codename generator
nsacodenamegenerator dot com is no more outputs random two words together in capital letters

tar exclude files or directories
If you want to exclude only one file or directory you should use as --exclude=file_or_directory
